The face is a result of the union of different structures. One of the most important structures of the face is the chin. In this way, depending on the projection and shape of the chin and its relationship with the rest of facial structures, the facial aesthetic result will be positive or negative.
Therefore, by modifying this with facial implants or through the filing of mandibular bone we will be able to improve the proportion and facial profile.
The most common techniques are the increase or decrease of the projection of the chin.
